Ceramic Tile over Terrazzo

I plan on installing ceramic tile in my bedroom, after pulling up the ugly existing carpet we discovered terrazzo underneath. Can I lay the ceramic tile directly over the terrazzo or does there need to be some type of sub floor and if so what is the best type of sub floor to use?

You can go over it provided there are no cracks. If there are cracks you will need a crack isolation membrane like Ditra. Available from:

Thanks, this is very helpful. The floor is in excellent condition so I don't think I need the membrane but what would I use to scarify the floor?

Terrazzo can be beautiful sure you want to cover it? Another option would be to bond Nobleseal to the substrate with Noblebond 21 which does not require the Terrazzo to be scarfied but it does need to be free of wax,dirt ect. www.noblecompany.com waterproofing,crack,& sound isolation

Fine split on ceramic tiles

Howdy all, In my home that is less than 2 years old, I found two ceramic tiles that have a very small split that runs through them. They are in an out of a way place that no one walks in, e.g. one in a corner and the other near a bath tub. Can I patch these and then seal them somehow? Both tiles are very firm and no noticable signs of movement. I prefer to patch them now rather than replacing them. Thanks SteveRead More

tile grout

We recently installed ceramic throughout the house, replacing truly hideous sea foam green carpeting. We were thrilled with the tile and chose mocha colored grout from Lowe's to compliment it. The grout dried a washed out mud color, no brown in it at all. We have approximately 1100 sq ft of mud room flooring. Before we seal it, we would like to know if there is anything we can do to perk up the grout. The color on the Lowe's chart was a nice chocolate brown. This isn't even close.Read More
